The Bullpen: Gambling Inside Nevada State Prison

For roughly 35 years, Nevada State Prison in Carson City contained an inmate-run gambling operation known as the Bullpen. Prisoners dealt and bankrolled games, supplied security and wagered in a closed economy using prison money called brass. This was an acknowledged part of prison life, not merely a secret poker game in a cell.

Why this history matters

The contradiction was striking: Nevada regulated commercial casinos, yet this casino inside a state institution had no Nevada gaming license. Its survival depended on wardens who tolerated or defended it. Its closure in 1967 reflected a change in prison administration and ideas about rehabilitation.

Chapter 01

Gambling behind the walls

The operation developed around 1932, shortly after Nevada legalized wide-scale casino gambling in 1931. The timing links it to the state's broader acceptance of wagering, although the exact first authorization within the prison remains uncertain. The Bullpen became a recognized recreation space within an institution otherwise organized around confinement, labor and discipline.

Prisoners worked in activities such as quarrying, printing, bookbinding and manufacturing. Gambling offered another way to occupy time, but within a coercive setting where earnings and personal freedom were limited. That setting distinguishes the Bullpen from every public resort casino.

Chapter 02

Inmates as bankers, dealers and players

The National Register history identifies craps, poker, blackjack, gin rummy and sports betting. Individual inmates ran and bankrolled games: the person operating a table had to possess the capital to pay winners. Reputation and access to money therefore shaped who could act as banker and who remained a customer.

A share of proceeds supported the inmate welfare fund. Later newspaper transcriptions give a ten-percent figure, but the precise accounting rule is less firmly established than the broader welfare contribution. Likewise, no reliable complete table count, schedule or betting-limit list is available.

The casino was not open to ordinary tourists. Later reporting describes invited civic visitors, including local club members and government officials, sometimes playing there. These were authorized guests inside a controlled institution, not evidence of public walk-in access.

Chapter 03

Brass: money within the prison

Prison-issued brass tokens connected the games to everyday purchasing power. The best-supported standard denominations run from five cents through five dollars, including ten, twenty-five and fifty cents and one dollar. Brass was both a physical medium and a prison term for money.

The casino's early-1930s origins should not be confused with the dates of particular token issues. Official summaries identify a later minting period, while specialist catalogs list dated varieties from several years. A dated piece proves that a token variety existed; it does not prove every piece circulated at a gaming table or that all denominations were issued simultaneously.

Surviving sets, including a six-denomination 1962 display set, make the prison economy unusually tangible. These objects are institutional currency, not simply miniature versions of commercial Las Vegas chips.

Chapter 04

Why wardens defended the casino

Warden M. L. Penrose argued that gambling could teach practical banking skills and allow a successful prisoner to accumulate money for release. Later wardens also defended supervision over outright prohibition. Art Bernard was reported as believing gambling could not realistically be eliminated; Jack Fogliani described it as a necessary evil.

Those arguments reveal administrative policy, not proof that the games reliably rehabilitated prisoners. A 1957 account attributed to Bernard warned that most players went broke. The same system that offered occupation and status could consume scarce wages and reinforce inequalities among inmates.

The book Pots O' Gold is associated with Penrose's defense of prison life, but later scholarship connects its authorship to inmate Jack Meredith. That authorship issue matters: a text presented through a warden's name may also reflect the work and perspective of a prisoner.

Chapter 05

The room and the prison yard

Preservation accounts describe sandstone Bullpen structures along the south side of the prison yard. Later summaries sometimes compress them into one casino building. Legislator Melvin Close remembered a small green building, dealers with rolled sleeves and eyeshades, and an inmate manager who invited him to lunch.

These descriptions need not refer to precisely the same view or phase, but they should not be forced into a single invented floor plan. The secure conclusion is that gambling occupied a distinct and recognized part of the prison's recreation environment. Archival photographs and surviving site remnants are more reliable guides than modern imagined casino interiors.

Chapter 06

A failed bill, then an administrative shutdown

In 1967, Assembly Bill 218 proposed prohibiting gambling at the prison. It failed in the Senate. Nevertheless, Governor Paul Laxalt's new warden, Carl Hocker, ended the operation through prison administration. Preservation accounts say Hocker asked gaming authorities whether the prison held a license and learned that it did not.

The absence of a license helped expose the fragility of a decades-old tolerated arrangement. Hocker regarded gambling as degrading and nonconstructive, promoting volleyball, table tennis and painting instead. The Bullpen structures were demolished that year.

The prison itself closed in 2012 and later became a historic site. Brass tokens and photographs now preserve a practice that once seemed ordinary enough to administrators to continue for decades. The Bullpen illustrates how Nevada's acceptance of gambling could reach even behind prison walls, and how abruptly an institution could redefine acceptable recreation.
